for genoil
for ccminer i use 1.8.2 with -i 23 no special parameter (but also not specifing intensity is giving me same results)
With these options, at stock clocks I get about 195MH/s LBC and 6.7MH/s ETH (ETH-only shows 25MH/s, LBC-only shows 278MH/s). It's difficult to see exact hashrates since both LBC and ETH miners show various numbers all the time in this mode. Sometimes Genoil shows 12MH/s, a couple of times I even saw 15MH/s, but average hashrate is 6.5...7MH/s. LBC miner shows more stable numbers, 180-210MH/s, average is 195MH/s.
With my miner at "-dcri 500" I get 147MH/s LBC and 13.7MH/s ETH.
So right now I don't see that Genoil+ccminer faster/better. However, I agree that LBC is not very good coin for dual mode anyway, it takes too much resources so ETH speed suffers.
